SPECIPICATIQN forming part of Letters Patent No. 349,190, dated September 14, 1886. Application filed DcccmbcllS. 1885. Serial No.186,030. (No model.)

Improvements in Vheel-Hubs; and l do here-A by declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which lo form a part of this specification.

This invention relates to that class of wheelhubs for vehicles comprising, generally, a central wooden part orhub and an exterior metal band or shell encircling the hub and provided with sockets continuous with the spoke-mor- 'tises of the hub, to engage and additionally ustain the parts of the spokes adjacent to the iub.

rlhe invention consists in the matters herezo inafter described, and pointed out in the Vappended claim.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective view of a hub constructed in accordance with my Fig. 2 is a central' axial section of the same, taken upon the line indicated by w w of Fig. 3. Fig. Bis afragmentary transverse section t-hrough the hub and metal band shown in Fig. 2, taken upon line x x of said figure.

3o Fig. 4 isa detail sectional View similar to Fig.

3, illustrating another means for securing together the collars or flanges forming the metallic band surrounding the wooden hub. Fig. 5 is a det-ail sectional view taken upon line x w of Fig. 4.

A is the central or main wooden part of the hub, provided with the usual mortises, a, for the spoke-tenons.

B B are two iianged collars encircling` the 4o hub, and together forminga metal band or annulus for sustaining the inner ends of the spokes.` The said collars B and B are arranged with their adjacent faces i'lush with the side walls of the spoke-mortises, one of said 4 5 collars, B, being provided with wedge-shaped projections b, cast integral with the said collar B', and secured to the collar B, so as to form a series of spoke-sockets, b', continuous with the mortises c.

5o C are the spokes, made with the usual tenthe collar B is provided with an extension or shell, B2, which is prolonged to cover the entire inner end of the Awooden part of the hub.

The parts or projections b upon the collar B are formed in such manner as to make the sockets or recesses b ofsu'fiieient width in their outer parts to receive the unreduced inner end of the spoke, said projections b being provided at their inner ends adjacent to the wooden hub with ribs or flanges b2, constructed to reduce thewidth of the inner parts of the sockets to the same size as the spoke-mortises a, the shoulders c' upon the spokes C being properly located to engage said iianges b2, as clearly shown in Fig. 3.

One means of fastening the free ends of the projections b to the collar B is shown in Figs. 1, 2, and 8, in which the said projections are provided upon their ends with integral studs b3, which are inserted through holes b4, formed their outer ends, to prevent their withdrawal from the said holes, the metal parts or the collar B being in this case made ot' malleable metal, in order to enable the said studs to be headed, as described. As a preferred construction, and as herein illustrated, the holes b* are made of conical shape, and the studs b are upset to fill the said holes, so as to make the ends of the headed studs approximately flush with the outer surface of the flange B', as clearly shown in the drawings.

Another construction in means for holding the collarsB and B together is shown in Figs. 4 and 5, in which separate rivets D areinserted through the collars B and B and suitably headed upon their ends exterior to the said collars, said rivets being constructed to pass through circular bolt apertures b5 and c?, formed half in the projection b and half in the spokes'C. This construction has the advantage of holding the spokes from coming out without materially weakening the latter,while at the same time affording a rigid support for the outer or free ends of the projections b.

To enable the several parts to be readily as; semloled or brought together,with the recesses b opposite the spoke-tenons a and with the collars B and B in proper relative position, inwardly-proj ecting ribs or iins b b7 arc pret'- erably cast upon the collars B and B,respect ively, said ribs or 'iins being adapted to fit and in the flange B, and upset or headed upon IOO enter a longitudinal groove, a', Figs. 2 and 3, formed in the exterior surface of the wooden hub A. The exterior surface of the wooden hub A and the inner surface ot' the collars B and B are preferably lnade conical or taperin g', and with their greatest diameter at the j oint between the collar B and the projections b b, this construction bein eused for convenience in casting, and to enable the collars to be driven tightly and innnovabl y upon the hub.

An obvious advantage ot' the construction described in the spoke-sockets b,whercby said sockets are provided with ribs or Hang-es b2 adjacent to the wooden partot' the hub, is thatthe portions ofthe spokes containing' the shoulders c are contained within the said sockets and supported by the walls ot' the latter,where by liability ot' breakage at the point where the said shoulders are i'orincd is obviated, this, as is well known, being' the point where the spoke is inost liable to break. The anges bl, furthermore, afford a wide bearing-surface on the parts ol' the projections b, which rest in contact with the hub. Said ianges also aid in rigidly holding` the spokes in place, inasmuch as when pressure is applied to the outer ends ot' one of spokes, tending to throw itlaterally, the contact of the end portions ot' the shoulders c with the said flanges will operate, in addition to the clamping action of the collars B and B', to rcsist any displacement ofthe spoke.

In the particular construction illustrated the shoulders c', instead of being made square, are inade rounded or concave in forni to lessen liability of breakage at the point at which the tenon joins the body of the spoke. The construction in which the collars B and B are united by studs b3, cast integral with the proj eetions b, is for several reasons preferred, and is made the subject of claim herein.

Itis entirely obvious that in carrying,- out my invention the collars B B may be extended to cover the exterior of the wooden hub to a greater or less extent, as desired, the collar B, as before stated, being' herein shown as extended to the inner end ofthehub. The collar B', as illustrated, is inade et' sutticient width only to provide a sufficient bearing therefor; but said collar may be also extended to t'orm a shell or case covering the entire wooden suri'ace ot' the hub outside ot' the spokes. This construction is illustrated by dotted lines in Fig. 2, which show the said collar B extended to lneet a band, E, such as is usually placed at the outer end ot' the hub.

As shown in Fig. 2, the wooden part ot'4 the hub is providcdwith a central passage or opening, A', adapted to be afterward realncd out to tit a box ot' the size which it is desired to use. The said opening will be usually enlarged su t'- ficiently to allow the inner ends ot' the spoketenons to bear upon the outer surtace et' the box, as is shown in Fig'. 3, in which F indicates the box in place within the hub.

I claiin as iny invention- The combination, with the wooden hub A, provided with lnortises (L for the sjrmkc-tenons. ot' inetal collars B B, formingr an annular metal band encircling' the hub, one ot' said collars being provided with projections l1a\'illgl'ilrs or flanges b adjacent to the wooden hub A, whereby are formed a series ot' spoke-sockets, b', adapted to receive the inner ends ot' the spokes, and adapted to tit the spoke-tenons at their inner portions, substantially as described.

In testimony that I claim the foregoing as my invention I afiix my signature in presence of two witnesses.
